as found convenient and desirable. One or more of the side walls are-provided with tabs which extend from the free edges thereof. These tabs may be formed on either the cover portion, the body portion or both. When the body and cover portions are telescoped together in closed position, the tabs are adapted to be bent over to lie against and be adhesively secured to the adjacent bottomwall after the box has been packed with the merchandise. The box can then be shipped in this condition and can be easily and quickly opened by the merchant or user by simply tearing or cutting the tabs free from the side walls of the body or cover portion to which they are joined.

If desired, the body, cover portions or both may be provided with double ply side and end walls to give the box additional strength. If the box is so made, the sealing tabs may be cut from one of the side flaps comprising the side walls. The tabs as thus formed require no extra material and no waste results from the making thereof.

An object of this invention is to provide a shipping box which can be economically, quickly and securely sealed after the same has been packed with merchandise and which further can be quickly and easily opened by the merchant or user without injuring or defacing the box.

Another object of my invention is to provide a box comprising body and cover portions adapted to telescope together having means for quickly, effectively and economically sealing said portions together after the container is packed, said means being easily and quickly manipulated to permit separation of the body and cover portions with- 5 out defacing the same.

Still another object of my invention is to provide a box comprising body and cover portions which may be economically constructed on automatic machinery, which is strong and durable, attractive in appearance and which can be easily and quickly sealed after the goods are packed therein and opened with speed and facility when access to the goods are desired.

Other objects of this invention will become ap- 5 parent as the disclosure is proceeded with.

Although the novel features which are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, the invention itself, as to its objects and advantages, and the manner in which it may be carried out, may be better understood by referring to the following description taken in connection with the accompanying drawing forming a part thereof, in which.

Fig. 1 is a face view of an extended blank from which the body or cover portion of the box may be formed;

Fig. 2 is a perspective view of the completed box showing the body and cover portions telescoped together and sealed by means of the sealing tab;

Fig. 3 is a perspective view of the blank shown in Fig. 1 as it appears partially assembled and it may constitute either the cover or body portion of the box;

Fig. 4 is a perspective view of the blank shown in Fig. 1 completely assembled, the box portion shown being the counter part of the box portion shown in Fig. 3;

Fig. 5 is 'a face view of an extended blank from which a modified form of body or cover portion may be made;

Fig. 6 is a perspective view of the cover portion of the box as formed from the blank 'shown in Fig. 5; and

Fig. 7 is a perspective view of the body portion of the blank which may be formed from a blank shown in Fig. 5.

Like reference characters denote like parts in the several figures of the drawing.

There is shown in Fig. 1 a blank of paperboard or other suitable material from which the body as well as the cover portion of the box may be made. The blank comprises generally bottom wall 10 having side walls 11 defined therefrom by the score lines 12 and end walls 13 defined from the bottom walls 10 by the score lines 12a. The box portion may be given added strength and rigidity by providing side flaps 14 hinged to the side walls 11 along the score lines 15. Likewise, end flaps 16 hinged to the end walls 13 along the score lines 1'7 may also be provided.

To secure the box portion in assembled position a tongue 18 extending from and hinged to each end of the side flaps 14 along the score lines 20 may be provided. Similarly, tongue 19 extending from and hinged to each end of the side walls 11 along the score lines 20 may also be provided.

In assembling the container adhesive, glue or other securing means 9 is coated onto the side flaps 14 and end fiaps 16. The side flaps 14 are then folded over the side walls 11 and adhere thereto by reason of the glue 9. It will be noted that the tongue 18 will then overlap the corresponding tongue 19, shown more clearly in Fig. 3. The side walls 11 are then bent along the score lines 21 substantially at right angles to bottom wall 10. The tongue 19 is then bent inwardly, as shown in Fig. 3. The side walls are bent at right angles to the bottom wall 10 and the end flaps 16 folded inside the box and over the tongues 18 and 19, the walls being secured together by means of the glue 9 positioned therebetween. A box portion having double ply side and end walls is thus provided.

The body portion of the boxmay be constructed in the manner above described, although it is not essential that the end and side walls be made of double ply material as above described. When the blank shown in Fig. 1 is to'be used as a cover portion, a cut 21 is provided in the end flaps 16 or in the side flaps 14, whichever is the most convenient or desirable. The cuts 21 define sealing tabs 22 which are hinged to the end walls 13 or side walls 11. For simplicity and illustration, I have shown cuts 21 as provided in the end fiaps 16 only. The cuts 21 define the sealing tabs 22 which are hinged to the end walls 13 along the score lines 17.

It will be seen that when the box has been assembled as shown in Fig. 3, the sealing tabs 22 will project upwardly from the free edge of the end walls 13. When the cover portion B of the box shown in Fig. 3 is telescoped over the body portion A, shown in Fig. 4, the tabs 22 may be bent over so as to lie fiat against the bottom wall 10 of the bodyportion. The adhesive g applied to the tabs-22 secures the tabs to the bottom wall of the box, presenting a complete and effective seal which is easily and quickly applied after the merchandise has been packed therein.

It is understood that the'sealing tabs 22 may be applied either to the body portion or the cover portion of the box or both as found convenient and desirable. Also, single ply side and end walls may be used, but it is advantageous and economical to make the side walls, from which the sealing tabs extend, of double ply material, since these walls receive the greatest strain.

1 have shown in Fig. 5 a box portion of slightly modified construction. This portion comprises a bottom wall 30 having side walls 31 hinged thereto along the score lines 32. The end walls 33 are hinged to the bottom wall 30 along the score lines 34. Side fiaps 35 hinge to the side walls 31 along the score lines 36 and'end flaps 37 hinge to the end walls 33 along the score line 38. Tongues 39 and 40 extending from each end of the side fiaps 35 and the side walls 31 respectively, adhere to the glued end flaps 3'! to hold the box portion in assembled relationship.

The blank shown in Fig. 5 similar to that shown in Fig. 1 except that a plurality of sealing tabs 4.2 are'provided which are cut out from the side flaps 35 of the blank. A plurality of sealing tabs are found useful and desirable where the box is of considerable length, as shown in Figs. 6 and 7, and where the boxmust carry considerable weight. It is understood, however, that the sealing tabs 42 may be positioned in any location most desirable for greatest strength and most effective sealing of the container.

If desired, openings or holes 23 may be cut in the side walls 11 and sid flaps 14 of the blank, as shown in Fig. 1, to provide a finger grip facilitating removal of the body and cover portions comprising the box.

It is understood that either the body or cover portion of the box may be provided with sealing tabs or both portions may be provided with these tabs as found most convenient and desirable. The body and covering portions may be formed of separate parts or may be hinged together in any desirable manner. Further, the side and end walls may be formed of single ply or double ply material, although it has been found advantageous to make the walls which carry the tabs of double ply material so that adequate strength may be assured.

While certain novel features of the invention have been disclosed and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes may be made by those skilled in the art without departing from the spirit of the invention.

What is claimed is:
